It was a good video, nice clear expression of the issues you found.
Interesting, I can see some possible issues with instability on significant off camber, but that is only a 100 lb tent, you should be able compensate. Of course your jeep is pretty light so it maybe it is not a ideal setup if you want do stuff like rock crawling.
I have the same tent on top of my Discovery II, as you noted no issues on -road, but clearance will be interesting on a few trails.
As to setup it took me about 20 minutes so that is pretty valid.
The ladders were something I thought about myself you get in a odd spot or softer ground then they could be annoying, a piece of plywood and a couple of 2x4 chunks can help with that. And I have them as a jack base anyway
The steps in the rain, slippery I am sure. Anti skid tape will help in my case being the in the PNW wet is going to happen.
The gymnast yes I get that, I have a hockey stick I use to pull the zipper across the front as well as other tough spots, and tuck the front in when folding. The hockey stick works pretty well as a can the tent open in the space measure too. But I have a metal steps and space to stand on the rear of my Disco, not a mudder or rock crawler so different setup
Other that I not found it to be all the terrible so far, but limited use due to the whole COVID thing.
Night lighting for the ladder is my next thing, getting up to pee is going to happen and a nice rechargeable not too bright red light would be nice
